Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14.February 20212
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Guideline study with acceptable restrictions. Valid method according to company guideline /standard operating procedure
- Principles of method if other than guideline:
- Differential thermal analysis (DTA)
- Type of method:
- other: Differential scanning colorimetry (DSC)
- Key result
- Melting / freezing pt.:
- 269 °C
- Decomposition:
- yes
- Decomp. temp.:
- 276 °C
- Executive summary:
The DTA recorded a melting point of 269°C and decomposition from the melting substance at onset temperature of 276°C.
Reference
An exothermic decomposition starts at 276°C. Because of the overlap of endothermic and exothermic processes, the energy measured for the exothermic process (945 J/g) is less than the true decomposition energy. The product begins to melt at 269°C.
Description of key information
Melting point at 269°C. Thermal analysis (Differential scanning colorimetry (DSC)).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 269 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
